Opasnet Calc is a computing system where the user can easily perform simple or complex calculations on a page in Opasnet based on values given by the user or found from the page or in Opasnet Base.

Scope

What is a method for performing calculations in Opasnet such that

• the input values may come from
  • Opasnet Base,
  • a wiki table on an Opasnet page,
  • an input form on an Opasnet page so that the user can enter the values,
  • any other source reachable by the R software on the Opasnet server;
• the computations may be performed by
  • Simupedia,
  • R code written on the Opasnet page within <rcode></rcode> tags,
  • R functions stored on the Opasnet server and called from the Opasnet page,
  • R code that the user writes directly to an input form on an Opasnet page; and
• the results may be retrieved to
  • the screen for the immediate and temporary use by the user,
  • the Opasnet page so that they are permanently visible to all readers of that page,
  • Opasnet Base,
  • a CSV file that the user can download.

Rationale

We need smooth interfaces between the wiki, the R, and the Opasnet Base.

In one way of using this, the input form a user may use should look something like the Google form. One user can develop a form and the calculations behind it, and other users just show up and use the form either by using default values of filling cells with their own values.
